Answer:

The placebo effect

Explanation:

The placebo effect in psychology refers to a situation in which participants in a research receive beneficial effects due to the administration of an inactive substance or a sham treatment. The positive beneficial effect received can then be attributed purely to believe and not to the treatment itself. A placebo treatment could produce a real healing effect like a true medical or psychological treatment.

The participants who received the sugar believed it to be a memory enhancing treatment hence the slight increase in memory capacity due to placebo effect.

What type of force caused the folds shown in the above cross section
valkas [14]
The folds in the photograph above were caused by compression at a thrust fault or a convergent plate boundary. Compression usually occurs where two tectonic plates converge or collide. The compression will cause rocks to fold upwards and this upward folding over time can lead to the formation of extensive fold mountains. Examples of fold mountains include the Alps, Andes, and the Himalayas.
